Shear walls of limited ductility

A comprehensive review of the state of the art in the design of earthquake resisting ductile structural walls is presented. The material has been compiled from the technical literature, the deliberations within the New Zealand National Society for Earthquake Engineering and research efforts at the University of Canterbury. The paper attempts a classification of structural types and elaborates on the hierarchy in energy dissipation. After a review of available analysis procedures, including modelling assumptions, a detailed description of capacity design procedures for both cantilever and coupled shear wall structures is given. The primary purpose of capacity design is to evaluate the critical design actions which can be used in the proportioning and reinforcing of wall actions which can be used in the proportioning and reinforcing of wall sections. An approach to the estimation of structural deformation is suggested. To satisfy the ductility demands imposed by the largest expected earthquake, detailed design and detailing recommendations are given and the application of some of these is presented in an appendix.

The paper deals with the design requirements for reinforced concrete diaphragms. Although diaphragms are primary members  of the seismic force resisting system, ductile detailing of diaphragms is not considered to be required. While the design of diaphragms in regular framed buildings is straightforward, the analysis of transfer diaphragms involves more complex design criteria. Special considerations related to precast diaphragms are dealt with in more detail.

Foundations for shear wall structures

After defining design criteria in general for foundations of earthquake resisting reinforced concrete structures, principles  are set out which govern the choice of suitable foundation systems for various types of shear wall structures. The choice of foundation systems depends on whether the seismic response of the superstructure during the largest expected earthquake is to be elastic or inelastic. For inelastically responding superstructures, preferably the foundation system should be designed to remain elastic. For elastically responding superstructures, suitable foundation systems may be energy dissipating, elastic or of the rocking type. Design criteria for each of these three foundation types are suggested.
